Part of the Swedish Empire
The history of Latvia between 1621 and 1721
During the Polish–Swedish War (1600–1629) Riga and the largest part of Duchy of Livonia came under Swedish rule in 1621. During the Swedish rule Vidzeme was known as the "Swedish Bread Basket" because it supplied the larger part of the Swedish Kingdom with wheat. The rest of Latvia stayed Polish until the second partition of Poland in 1793, when it became Russian.
In 1632 the Swedish king Gustavus Adolphus founded Dorpat University which became the intellectual focus for population of Livonia. The translation of the whole Bible into Latvian in 1685 by Johann Ernst Glück was subsidized by the Swedish government. Also the schools for Latvian speaking peasantry were set up in the country parishes.
Riga was the second largest city in the Swedish Empire at the time. Together with other Baltic Sea dominions, Livonia served to secure the Swedish Dominium maris baltici. In contrast to Swedish Estonia, which had submitted to Swedish rule voluntarily in 1561 and where traditional local laws remained largely untouched, the uniformity policy was applied in Swedish Livonia under Karl XI of Sweden: serfdom was abolished in the estates owned by the Swedish crown, peasants were offered education and military, administrative or ecclesiastical careers, and nobles had to transfer domains to the king in the Great Reduction. These reforms were subsequently reversed by Peter I of Russia when he conquered Livonia.
Inflanty Voivodeship
After the Polish–Swedish War (1600–1629) only the Southeastern part of the Duchy of Livonia ramained under Polish-Lithuanian rule. The Catholicism became the dominant religion in this territory known as Inflanty or Latgale as a result of Counter-Reformation.
